Texas Instruments TMS320F28030PAGQ

Overview

TMS320F28030PAGQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated analog peripherals, designed for digital power and motor control in automotive-grade systems. It delivers 16.67-ns instruction cycle time, 16K × 16-bit on-chip Flash, 6K × 16-bit SARAM, 12-bit ADC (3-MSPS, 16 channels), and 14 ePWM channels - enabling closed-loop control in EV charging modules and DC/DC converters.

For engineers reviewing the TMS320F28030PAGQ datasheet, TMS320F28030PAGQ pinout, TMS320F28030PAGQ application, or TMS320F28030PAGQ equivalent, key selection considerations include AEC Q100 qualification (–40°C to 125°C), TQFP-64 package compatibility, CLA absence, and eCAN/I²C/SPI/SCI serial interface support for system-level communication and diagnostics.

Technical Context

The TMS320F28030PAGQ implements a Harvard-architecture C28x CPU with atomic operations and fast interrupt response, paired with a unified memory model for efficient C/C++ execution. Its peripheral set includes three 32-bit CPU timers, PIE-interrupt expansion, and GPIO multiplexing across 45 pins - all operating from a single 3.3-V supply without sequencing requirements.

Analog integration centers on a 12-bit ADC with 500-ns conversion time, dual sample-and-hold, internal VREFHI/VREFLO references, and direct routing of comparator outputs to PWM triggers. The device lacks the Control Law Accelerator (CLA) and high-resolution PWM (HRPWM) found in higher-tier F2803x variants, distinguishing its real-time processing scope.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28030PAGQ?

The TMS320F28030PAGQ operates at a maximum CPU frequency of 60 MHz, yielding a 16.67-ns instruction cycle time. This timing is fixed by the internal PLL configuration and applies across the full –40°C to +125°C temperature range. All performance specifications in the datasheet, including ADC conversion rate and PWM resolution, are validated at this clock speed. The TMS320F28030PAGQ does not support overclocking or frequency scaling beyond 60 MHz.

Does the TMS320F28030PAGQ include a Control Law Accelerator (CLA)?

No, the TMS320F28030PAGQ does not include a Control Law Accelerator. The CLA is present only in the TMS320F28033 and TMS320F28035 variants within the F2803x family. The TMS320F28030PAGQ relies solely on the C28x CPU for real-time control computations. This distinction affects computational headroom for parallel control loops but maintains full code compatibility with CLA-enabled devices at the application layer.

What serial communication interfaces are integrated into the TMS320F28030PAGQ?

The TMS320F28030PAGQ integrates one SCI (UART-compatible), two SPI modules, one I²C module, one LIN module, and one eCAN module - all with 4-level FIFO buffers. These interfaces operate independently and can be enabled simultaneously. The TMS320F28030PAGQ does not include USB or Ethernet peripherals. Each interface supports standard protocol framing and error detection, with dedicated interrupt vectors routed through the PIE block.

How many analog-to-digital converter (ADC) channels does the TMS320F28030PAGQ support, and what is its conversion speed?

The TMS320F28030PAGQ features a 12-bit ADC with 16 input channels (ADCINA0–ADCINA7 and ADCINB0–ADCINB7), capable of 3 million samples per second (MSPS). Conversion time is 500 ns per sample, with dual sample-and-hold circuitry enabling simultaneous sampling of two channels. The ADC uses internal VREFHI/VREFLO references and supports ratio-metric measurement modes essential for current sensing in power electronics applications.

Is the TMS320F28030PAGQ pin-compatible with other members of the F2803x family in the same package?

Yes, the TMS320F28030PAGQ is pin-compatible with all other F2803x devices offered in the 64-pin TQFP (PAG) package, including TMS320F28031PAGQ, TMS320F28032PAGQ, TMS320F28033PAGQ, TMS320F28034PAGQ, and TMS320F28035PAGQ. Pin assignments, power domains, and peripheral signal mappings are identical across these variants. However, differences in on-chip resources (e.g., Flash size, CLA presence, HRCAP count) require firmware validation during substitution.
